On the road of pursuing independent research and development, domestic brands are making their own efforts. Everyone has their own goals, for example, vivo is dedicated to imaging, last year launched the professional image chip V1, and earlier in the "vivo dual-core image technology communication meeting", vivo launched a new upgrade of the professional image chip V1 +, it is not only a professional image chip, but also a display performance chip, "double core attack" has brought a new benchmark of the second generation of dual-core flagship.
It is reported that the professional image chip V1+ was jointly created by the technical research and development team jointly created by vivo and MediaTek. After 350 days of in-depth collaborative development, the team has achieved the adjustment and translucency of the professional image chip V1+ and the Tianji 9000 chip, releasing the strongest performance of the Tianji 9000 chip. In order to improve the energy efficiency ratio of Tianji 9000, Vivo used the algorithm to adjust the CPU resource allocation strategy, and after complex debugging work, it finally reduced the power consumption of Tianji 9000 and improved the energy efficiency ratio.
Of course, the optimization of the chip is not a short time, but a protracted battle. In order to make the experience more smooth, vivo has also established a set of "user use scenario fluency model", the purpose is to identify the differences in user use scenarios, to allocate the appropriate computing power. With the blessing of "multi-pronged" methods, the overall animation fluency under high load scenarios has increased by 50%, and at the same time, with the new memory resource management scheme, the virtual cache unit has been established to improve the data processing speed, and the anti-aging fluency experience has been realized for up to 36 months.
In other words, a combination of high performance and low power consumption can be achieved. On the other hand, the professional image chip V1+ has greater innovation in imaging, and the three major algorithms of 3D real-time stereoscopic night scene noise reduction, MEMC interpolation and AI super-division are hardware packaged, which realizes the characteristics of good scheduling, fast speed and high energy efficiency, whether it is still photos or moving images can obtain excellent clarity and fluency, and the battery life is more urgent and durable.
It is worth mentioning that the first generation of professional image chip V1 has an extraordinary night scene video shooting capability, and the new generation of professional image chip V1 + is more sophisticated, with video noise reduction algorithm to achieve the polar night video function of less than 1lux environment, with the lens module, the main chip and vivo self-developed image algorithm of the three-party empowerment, so that the mobile phone night video shooting reached the level of night vision, the mobile phone industry ranked first.
In terms of image experience, the professional image chip V1+ has realized full-link color management from four dimensions of detection, shooting, processing and display, and each image stored in the vivo mobile phone can have consistent color expression and perfectly restore the color texture of the natural world; the first self-developed XDR Photo technology allows the ultra-high dynamic range of the photo to be realized, and the highest brightness area can be increased by up to 350%, making the texture of the bright position more transparent, and the overall shadow tone more delicate and layered.
At the same time, the professional image chip V1+ also increased the ΔE of ZEISS natural colors by about 8.3% on the basis of about 15.5% compared with the past, and made the tonal appearance of ZEISS real colors more excellent through fine tone. It is not difficult to see that Vivo's deep cultivation in imaging technology has always been steadily moving forward, especially after self-developed chips have become the trend of the times, Vivo has invested great efforts in self-research and made great progress in imaging technology. The arrival of professional imaging chip V1+ means that vivo's self-developed chip is not limited to imaging, but also fully empowered by the performance experience.
